Embodiment Construction

[0035] Such as figure 1 As shown, the present invention includes a housing 1, a power supply 2, a traveling wheel 3 (crossing wheel), a knocking part, a cutting part (including a push rod and a cutting piece), and a remote control module.

[0036] The power supply 2 uses a lithium battery, which can provide about 1 hour of battery life. The battery has a capacity of 50AH, a full voltage of 12.6V, and a stable protection current of 10A. There is a voltage indication at the power switch.

[0037] The shell 1 includes a vertical vertical box 4 and an upper box body 6 and a lower box body 7 connected to the upper and lower positions on the same side of the vertical box 4, and the vertical box 4 may also be plate-shaped. The upper box body 6 is a lower side opening, and the lower box body 7 is a closed box body, and a power supply 2, a control module, a remote control module, etc. are installed inside. The vertical box 4 is fixedly connected with the upper box body 6 and the lowe...

Abstract

The invention provides a deicing device for an electric transmission line. The deicing device for the electric transmission line comprises a shell, a power source, two or more walking wheels, a beating portion, a cutting portion and a remote control device. The remote control device comprises a remote control module. The shell comprises a vertical box, an upper box body and a lower box body, wherein the vertical box is vertically arranged, the upper box body is connected to the front side of the vertical box, and the lower box body is sealed. A passing space where the electric transmission line passes is formed between the upper box body and the lower box body. An opening is formed in the bottom of the upper box body. The waking wheels are installed at the upper box body in the transverse direction. The lower half portions of the walking wheels extend out of the upper box body. The power source and the remote control module are installed in the lower box body. The walking wheels are connected with a walking wheel motor. Through site simulation tests, the deicing device can effectively walk on a single divided conductor and double divided conductors and stride across a spacer, and the beating function and the cutting function can be both effectively achieved under the remote control condition.

Description

technical field [0001] The invention relates to the field of power transmission line maintenance, in particular to a deicing device for power transmission lines. Background technique [0002] Icing of AC and DC transmission lines in winter is one of the biggest natural disasters in the power system. Rime is formed when cold raindrops fall on objects with a temperature below freezing (0°C). If it is condensed on the wire, it will form wire icing. If all wires within a range are encased in ice, this is icing. [0003] For high-voltage wires for long-distance power transmission, they rely on iron towers for support. Ice coating increases the load on the iron towers. Severe ice coating can make the iron towers unable to support these wires and collapse. However, if the insulator strings on the iron tower are covered with ice, they can only pull the brakes to stop the transmission of electricity, thus causing large-scale power interruptions. The icing on the line constitutes ...
